Astronomy Calendar 2021: When to watch complete moons, planets, eclipses and meteor showers

Published

on

Get ready for a year loaded up with stunning motivations to gaze toward the night sky.

There will be full moons, meteor showers, shrouds and planets obvious toward the beginning of the day and night skies across the world in 2021.

Meteor showers

The Quadrantid meteor shower on January 3 commenced the first of 12 meteor showers across 2021.

The biggest impediment to having the option to see meteor showers that are just obvious from specific sides of the equator – aside from your area – is the splendor of the moon. The more full the moon is, the harder it is to see meteors streak across the sky.

There is somewhat of a stand by until the following meteor shower, the famous Lyrids in April. The Lyrids will top on April 22 and will be best found in the Northern Hemisphere – yet the moon will be 68% full, as indicated by the American Meteor Society.

The Eta Aquariids follow before long, topping on May 5 when the moon is 38% full. This shower is best found in the southern jungles, yet will at present deliver a medium shower for those north of the equator.

The Delta Aquariids are likewise best seen from the southern jungles and will top between July 28 and 29 when the moon is 74% full.

Curiously, another meteor shower tops on the very evening – the Alpha Capricornids. Despite the fact that this is a lot more fragile shower, it has been known to deliver some splendid fireballs during the pinnacle. Furthermore, it will be noticeable for those on one or the other side of the equator.

The Perseid meteor shower, the most famous of the year, will top between August 11 and 12 in the Northern Hemisphere when the moon is just 13% full.

Here is the meteor shower plan for the remainder of the year, as indicated by EarthSky’s meteor shower standpoint.

  • October 8: Draconids
  • October 21: Orionids
  • November 4 to 5: South Taurids
  • November 11 to 12: North Taurids
  • November 17: Leonids
  • December 13 to 14: Geminids
  • December 22: Ursids

Full moons

Run of the mill of a typical year, 2021 will likewise have 12 full moons. (A year ago had 13 full moons, two of which were in October).

Here are the entirety of the full moons happening this year and their names, as per The Old Farmer’s Almanac:

  • January 28 – Wolf moon
  • February 27 – Snow moon
  • Walk 28 – Worm moon
  • April 26 – Pink moon
  • May 26 – Flower moon
  • June 24 – Strawberry moon
  • July 23 – Buck moon
  • August 22 – Sturgeon moon
  • September 20 – Harvest moon
  • October 20 – Hunter’s moon
  • November 19 – Beaver moon
  • December 18 – Cold moon

Solar and lunar eclipses

This year, there will be two obscurations of the sun and two shrouds of the moon – and three of these will be noticeable for some in North America, as indicated by The Old Farmer’s Almanac.

A complete overshadowing of the moon will happen on May 26, best noticeable to those in western North America and Hawaii from 4:46 a.m. ET to 9:51 a.m. ET.

An annular overshadowing of the sun will occur on June 10, obvious in northern and northeastern North America from 4:12 a.m. ET to 9:11 a.m. ET. The sun won’t be completely obstructed by the moon, so make certain to wear overshadow glasses to securely see this occasion.

November 19 will see a fractional shroud of the moon and skywatchers in North America and Hawaii will see it between 1 a.m. ET and 7:06 a.m. ET.

Also, the year closes with a complete shroud of the sun on December 4. It won’t be found in North America, however those in the Falkland Islands, the southern tip of Africa, Antarctica and southeastern Australia will have the option to spot it.

Visible planets

Skywatchers will have different occasions to detect the planets in our sky during specific mornings and nights all through 2021, as indicated by The Farmer’s Almanac planetary guide.

It’s conceivable to see the greater part of these with the unaided eye, except for removed Neptune, however optics or a telescope will give the best view.

Mercury will seem as though a splendid star toward the beginning of the day sky from February 28 to March 20, June 27 to July 16, and October 18 to November 1. It will sparkle in the night sky from January 15 to January 31, May 3 to May 24, August 31 to September 21 and November 29 to December 31.

Venus, our nearest neighbor in the nearby planetary group, will show up in the eastern sky on the mornings of January 1 to 23 and in the western sky at nightfall on the nights of May 24 to December 31. It’s the second most brilliant article in our sky after the moon.

Mars shows up toward the beginning of the day sky between November 24 and December 31 and will be obvious at night sky between January 1 and August 22.

Jupiter, the biggest planet in our close planetary system, is the third most brilliant item in our sky. It will be in plain view in the first part of the day sky between February 17 and August 19. Search for it in the nights of January 1 to 9 and August 20 to December 31 – yet it will be at its most brilliant from August 8 to September 2.

Saturn’s rings are just obvious through a telescope, yet the planet itself can in any case be seen with the unaided eye on the mornings of February 10 to August 1 and the nights of January 1 to 6 and August 2 to December 31. It will be at its most brilliant between August 1 to 4.

Optics or a telescope will help you detect the greenish gleam of Uranus on the mornings of May 16 to November 3 and the nights of January 1 to April 12 and November 4 to December 31 – however at its most splendid between August 28 to December 31.

Also, our most removed neighbor in the nearby planetary group, Neptune will be obvious through a telescope on the mornings of March 27 to September 13 and the nights of January 1 to February 23 and September 14 to December 31. It will be at its most brilliant between July 19 and November 8.

Starship is Chosen by Lunar Outpost to Transport the Rover to the Moon

Published

on

For NASA’s possible use, Lunar Outpost has chosen SpaceX’s Starship vehicle to transport the Artemis lunar rover it is developing to the moon.

The Denver-based business revealed on November 21 that it has reached a deal with SpaceX to use Starship to deliver the company’s Lunar Outpost Eagle rover to the moon. Neither the launch date nor any other details of the agreement were disclosed by the companies.

In April, NASA awarded contracts to Lunar Outpost and three other firms for the first phase of the Lunar Terrain Vehicle (LTV) program, which will help construct a rover for future Artemis missions. Each business was given a one-year contract to complete a preliminary design review (PDR) of their rovers. The government will then choose at least one of the companies to continue developing the rover.

Delivering the rover to the moon is the responsibility of the firms under the LTV program, which is set up as a services contract. When NASA no longer needs those rovers, those businesses will be allowed to use them for commercial purposes.

In an interview, Lunar Outpost CEO Justin Cyrus stated that the company chose SpaceX after receiving “great responses” from a number of businesses. He stated, “The reason we chose Starship is their technological maturation, the pace at which they move and the quality of that organization “It’s a vehicle that we think will be able to provide reliable landing on the lunar surface, and we know that they can get it done on the timelines we need.”

Although he did not reveal other vehicles his business investigated alongside Starship, Lunar Outpost developed the rover to be compatible with as many conceivable landing mechanisms as possible. “We need this vehicle to be compatible with multiple different lander providers, so that way we have the optionality, that way we have flexibility, and we can evaluate technical progress over time just to make sure we can derisk our commercial case.”

The team working on the rover is led by Lunar Outpost and consists of Leidos, MDA Space, Goodyear, and General Motors. After Lunar Outpost failed to reach a consensus regarding Lockheed Martin’s involvement in the project, Leidos took over as one of the partners on the “Lunar Dawn” team in September.

NASA astronauts recently drove a rover prototype for human factors testing as part of that team’s busy work to improve the rover’s design. Cyrus stated, “We learned what the astronauts really like and what we can improve upon,” 

In roughly six months, the contract’s first phase will come to an end with a PDR. In order to create the rover and acquire services for the following phase, NASA will then ask Lunar Outpost and the other two grantees, Intuitive Machines and Venturi Astrolab, to submit ideas.

Although Cyrus and other industry professionals are urging NASA to select multiple companies to provide redundancy, as the agency has done in other services programs like the Human Landing System, NASA officials have stated that budget constraints mean they are likely to select only one company for that next phase.

“NASA should pick two. Dissimilar redundancy for something this critical, I think, is the right choice,” he stated.

On November 13, Lunar Outpost revealed that it had raised a Series A round, but Cyrus stated that the business would not reveal the size due to competitive considerations. He said that the money would be used to develop the Lunar Outpost Eagle.

Citing commercial interest from potential clients, he noted that the company intends to continue working on the rover even if it is not chosen for the next stage of NASA’s LTV program. Regarding the funding, he stated, “This allows us to accelerate those plans pretty drastically,” “So, no matter what we’re going to be flying this vehicle on Starship.”

NASA and SpaceX Highlight Important Aspects of the Artemis cc

Published

on

As part of its Artemis program, NASA is collaborating with American businesses to create the human landing devices that will securely transport humans from lunar orbit to the Moon’s surface and back.

NASA is collaborating with SpaceX to build the company’s Starship Human Landing System (HLS) for Artemis III, the first crewed lunar landing in more than 50 years. In lunar orbit, Starship HLS would dock with NASA’s Orion spacecraft. Two Artemis crew members will then transition from Orion to Starship and descend to the surface, according to recently revised artist’s conceptual renders. Before returning in Starship to Orion, which is waiting in lunar orbit, the astronauts will gather samples, conduct scientific experiments, and examine the Moon’s environment there. SpaceX will conduct an uncrewed landing demonstration mission on the Moon before the crewed Artemis III mission.

In order to achieve a more comprehensive set of requirements for Artemis IV, NASA is also collaborating with SpaceX to further the development of the company’s Starship lander. These specifications include docking with the agency’s Gateway lunar space station for human transfers and putting greater mass on the moon.

In the artist’s idea, SpaceX’s Starship HLS is shown completing a braking burn before landing on the Moon, with two Raptor engines blazing. In order to lower the lander’s velocity before its final drop to the lunar surface, the burn will take place once Starship HLS leaves low lunar orbit.

NASA will learn how to live and work away from home, explore more of the Moon than ever before, and get ready for future human exploration of Mars with Artemis. NASA’s deep space exploration is built on its SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, as well as its human landing system, next-generation spacesuits, Gateway lunar space station, and upcoming rovers.

Chinese Rover Discovers Signs of Mars’s Ancient Ocean: Study

Published

on

Researchers claim that recently analyzed data from a Chinese investigator on Mars supports the body of evidence showing the planet originally had a massive ocean.

Zhurong is the name of the rover, or exploring vehicle. In 2021, it made its surface landing on Mars. Utopia Planitia is the region where the rover has been functioning. The American space organization NASA says that this region is a sizable plain in the northern hemisphere of Mars.

The scientists integrated information from Zhurong’s equipment with observations from spacecraft and satellites circling Mars. Geological elements that suggested an ancient ocean coastline were found in Utopia Planitia, according to the team’s studies.

Several characteristics, according to the experts, suggested that there was a sizable ocean on Mars billions of years ago. The troughs and channels found on the surface could have been created by water flowing across Mars.

Mud volcanoes, which most likely erupted in regions where there had been water or ice, may have produced them, according to earlier studies that looked at data on comparable surface features.

According to the researchers, the data indicates that both shallow and deep ocean conditions were probably present in the region. The results of a recent study were published in the journal Scientific Reports.

The study was primarily written by Bo Wu. At Hong Kong Polytechnic University, he works as a planetary scientist. According to Wu, “We estimate the flooding of the Utopia Planitia on Mars was approximately 3.68 billion years ago. The ocean surface was likely frozen in a geologically short period.”

On Mars, the hunt for water is closely related to the hunt for potential life. The planet might have once hosted microbial life if there is evidence of a former ocean.

Previous research indicates that Mars formerly had a sizable northern ocean. In 2022, one such study was published. Satellite photos of the Martian surface served as the basis for that study. Detailed maps of the planet’s northern hemisphere were created by combining the pictures. Analyzing the maps revealed indications of coastlines that were previously part of a vast ocean.

Evidence from a different study that was published in August suggested that Mars might have a sizable ocean located far below the surface. NASA’s InSight Lander served as the basis for that proof.

In May 2021, the Zhurong rover from China started gathering data. It ceased operations almost a year later, with mission planners stating that dust and sand probably had an impact on the power system. The rover nevertheless outlived its three-month mission.

According to the researchers, the data indicates that the ocean appears to have vanished approximately 3.42 billion years ago.

According to research co-writer Sergey Krasilnikov, the water that most likely filled the Martian ocean was “heavily silted.” At Hong Kong Polytechnic University, he works as a planetary scientist. Water-borne silt is a mixture of clay and sand that eventually settles on land.

Krasilnikov went on to say that the planet “…probably had a thick, warm atmosphere” when the Martian ocean would have been active.” “Microbial life was much more likely at that time,” he stated.

The latest discoveries do “provide further evidence to support the theory of a Martian ocean,” according to Wu of Hong Kong Polytechnic.

The study does “not claim that our findings definitively prove” that there was an ocean on Mars, he told the French news agency AFP. According to him, such evidence would probably necessitate a further trip to return items from Mars to Earth for additional analysis.
