17/1/2021 - The top space stories of the week!
One NASA mission on Mars will be listening for the landing of the latest Red Planet rover, the CIA releases thousands of declassified UFO-related documents and a Japanese asteroid-studying spacecraft starts a new multi-year journey into the solar system. These are some of the top stories this week from Space.com.
On Thursday (Jan. 14), Blue Origin successfully launched the reusable RSS First Step spacecraft in an uncrewed suborbital test flight from West Texas. It is the first upgraded New Shepard spacecraft for astronauts, and both its rocket and capsule successfully touched down after launch. Blue Origin is developing New Shepard to carry people and payloads to suborbital space and back.

The national meteorological service for the U.K., Autel Maxicom MK908p
. called the Met Office, made a recent forecast that suggests the concentration of carbon dioxide (CO2) in Earth's atmosphere will exceed a major threshold this year. CO2 stays in the atmosphere for a long time, according to forecast's lead researcher, and emissions from previous years causes levels to continue increasing. In 2021, they expect a 50% increase in atmospheric CO2 since the start of widespread industrial activity in the 18th century.

SpaceX's 21st space station cargo delivery mission for NASA wrapped up on Wednesday (Jan. 13) when a Cargo Dragon spacecraft returned to Earth off the coast of Florida. The Dragon CRS-21 mission launched on Dec. 6, 2020 and delivered 6,40 lbs. (2,903 kilograms) of supplies and science equipment to the crew onboard the International Space Station. This was the first Atlantic splashdown of a Cargo Dragon.

The CIA released more than 2,700 pages of declassified documents related to "unidentified aerial phenomena." The documents were released following several Freedom of Information Act (FOIA) requests filed over the last 25 years, according to the operator of The Black Vault, an online repository of UFO-related documents.

Astronomers found the most distant quasar known to science. It's so far away that the light reaching Earth from this quasar dates back to when the universe was just 5% of its current age. This quasar also hosts a supermassive black hole with a mass roughly the equivalent of 1.6 billion suns.

Japan's Hayabusa2 spacecraft is now on its way to a new asteroid after dropping off samples from its previous target to Earth in early December 2020. On Jan. 5, the mission team started powered navigation back out into the solar system to reach the 2,300-foot-wide (700 meters) asteroid (98943) 2001 CC21 for a flyby in 2026. A more in-depth visit to another space rock will occur in 2031, when it studies a small 100 feet (30 m) wide asteroid called 1998 KY26.

Scientists used data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the W.M. Keck Observatory in Hawaii to find an exoplanet, about 50% larger than Earth, that orbits one of the oldest stars in the Milky Way galaxy. The system is located nearby, about 280 light-years from Earth. The exoplanet is about our planet's size and density, but its average surface temperature of over 3,140 degrees Fahrenheit (1,726 degrees Celsius) means it is too hot to host any form of life as we know it.
