Copenhagen Suborbitals is the world’s only crewed, crowdfunded space program. In the future, a volunteer astronaut will fly to space on our home-built rocket. We do this on our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!

Mars 2020 is a Mars rover mission by NASA’s Mars Exploration Program that includes the Perseverance rover and the Ingenuity helicopter drone. It was launched on 30 July 2020 at 11:50 UTC, and will touch down in Jezero crater on Mars on 18 February 2021.

Perseverance will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. It will cache sample containers along its route for retrieval by a potential future Mars sample-return mission. The Mars 2020 mission was announced by NASA on 4 December 2012 at the fall meeting of the American Geophysical Union in San Francisco. The Perseverance rover’s design is derived from the Curiosity rover, and will use many components already fabricated and tested, new scientific instruments and a core drill.

Mars 2020 was the third of three space missions sent toward Mars during the July 2020 Mars launch window, with missions also launched by the national space agencies of the United Arab Emirates (Hope orbiter) and China (Tianwen-1, with an orbiter, lander, and rover). All three are expected to arrive at Mars in February 2021.

On Wednesday, December 9, Starship serial number 8 (SN8) lifted off from our Cameron County launch pad and successfully ascended, transitioned propellant, and performed its landing flip maneuver with precise flap control to reach its landing point. Low pressure in the fuel header tank during the landing burn led to high touchdown velocity resulting in a hard (and exciting!) landing.

Plants play a key role in mitigating climate change. The more carbon dioxide they absorb during photosynthesis, the less carbon dioxide remains trapped in the atmosphere where it can cause temperatures to rise. But scientists have identified an unsettling trend – 86% of land ecosystems globally are becoming progressively less efficient at absorbing the increasing levels of CO2 from the atmosphere.

The Crab Nebula has been studied by people since it first appeared in Earth’s sky in 1054 A.D. Modern telescopes have captured its enduring engine powered by a quickly spinning neutron star that formed when a massive star collapsed. The combination of rapid rotation and a strong magnetic field generates jets of matter and anti-matter flowing away from its poles, and winds outward from its equator. For the translation of these data into sound, which also pans left to right, each wavelength of light has been paired with a different family of instruments. X-rays from Chandra X-ray Observatory (blue and white) are brass, optical light data from Hubble Space Telescope (purple) are strings, and infrared data from Spitzer (pink) can be heard in the woodwinds. In each case, light received towards the top of the image is played as higher pitched notes and brighter light is played louder.

NASA’s Dawn spacecraft captured pictures in visible and infrared wavelengths, which were combined to create this false-color view of a region in 57-mile-wide (92-kilometer-wide) Occator Crater on the dwarf planet Ceres (in the main asteroid belt between Mars and Jupiter). Here, recently exposed brine, or salty liquids, in the center of the crater were pushed up from a deep reservoir below Ceres’ crust. In this view, they appear reddish.

Seen here is Cerealia Facula (“facula” means bright area), a 9-mile-wide (15-kilometer-wide) region with a composition dominated by salts. The central dome, Cerealia Tholus, is about 1.9 miles (3 kilometers) across at its base and 1,100 feet (340 meters) tall. The dome is inside a central depression about 3,000 feet (900 meters) deep.

Dawn’s mission is managed by NASA’s Jet Propulsion Laboratory, a division of Caltech, for the agency’s Science Mission Directorate in Washington. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. JPL is responsible for overall Dawn mission science. Northrop Grumman in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.
