MAVEN is the first spacecraft specifically designed to study the Mars upper atmosphere, in order to better understand the evolution of its climate. By measuring windspeed and direction near the top of the atmosphere, MAVEN has discovered that high-altitude wind currents are being disturbed by terrain features far below. This unexpected and surprising finding means that MAVEN can sense the presence of mountains and valleys on the surface of Mars while skimming the edge of space.

Mars 2020 is a Mars rover mission by NASA’s Mars Exploration Program with a planned launch on 17 July 2020, and touch down in Jezero crater on Mars on 18 February 2021.

The mission will seek signs of habitable conditions on Mars in the ancient past, and will also search for evidence—or biosignatures—of past microbial life. The rover is planned for launch in 2020 on an Atlas V-541, and the Jet Propulsion Laboratory will manage the mission. The mission is part of NASA’s Mars Exploration Program.

The Science Definition Team proposed that the rover collect and package as many as 31 samples of rock cores and surface soil for a later mission to bring back for definitive analysis on Earth. In 2015 they expanded the concept, planning to collect even more samples and distribute the tubes in small piles or caches across the surface of Mars.

In September 2013 NASA launched an Announcement of Opportunity for researchers to propose and develop the instruments needed, including the Sample Caching System. The science instruments for the mission were selected in July 2014 after an open competition based on the scientific objectives set one year earlier. The science conducted by the rover’s instruments will provide the context needed for detailed analyses of the returned samples. The chairman of the Science Definition Team stated that NASA does not presume that life ever existed on Mars, but given the recent Curiosity rover findings, past Martian life seems possible.

Northrop Grumman dicit:

The Cygnus system is a flight proven design incorporating elements drawn from Northrop Grumman and its partners’ existing, flight-proven spacecraft technologies. Cygnus consists of a service module and a pressurized cargo module. Cygnus is used to carry crew supplies, spare equipment and scientific experiments to the space station. The service module incorporates advanced avionics developed by Northrop Grumman and guidance and navigation components that allow for fully autonomous rendezvous with the space station. The avionics design fully meets all of the demanding NASA safety requirements imposed on human-rated vehicles. The pressurized cargo module is manufactured by Thales Alenia Space specifically for Cygnus.

Northrop Grumman dicit:

Northrop Grumman’s vision for the next step toward human space missions to Mars employs our flight-proven Cygnus advanced maneuvering spacecraft as a human habitat in cislunar space, the region between the Moon and Earth. In the early 2020s we would launch the initial habitat on NASA’s SLS rocket. Featuring a modular design, the habitat would serve both as a destination for crewed missions and as an unmanned testbed to prove-out the technologies needed for long-duration human space missions. The habitat is also envisioned as a base for lunar missions by international partners or commercial ventures. With additional habitation and propulsion modules, the habitat could be outfitted for a Mars pathfinder mission.

Mars 2020 is a Mars rover mission by NASA’s Mars Exploration Program with a planned launch on 17 July 2020, and touch down in Jezero crater on Mars on 18 February 2021. It 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 a potential future Mars sample-return mission.

The currently unnamed Mars 2020 mission was announced by NASA on 4 December 2012 at the fall meeting of the American Geophysical Union in San Francisco. The rover’s design is derived from the Curiosity rover, and will use many components already fabricated and tested, including different scientific instruments and a core drill.

The Artemis program is an ongoing crewed spaceflight program carried out by NASA, U.S. commercial spaceflight companies, and international partners such as ESA, with the goal of landing “the first woman and the next man” on the lunar south pole region by 2024. Artemis would be the first step towards the long-term goal of establishing a sustainable presence on the Moon, laying the foundation for private companies to build a lunar economy, and eventually sending humans to Mars.

In 2017, the lunar campaign was authorized by Space Policy Directive 1, utilizing various ongoing spacecraft programs such as Orion, the Lunar Orbital Platform-Gateway space station, Commercial Lunar Payload Services, and a yet-to-be-developed crewed lander. The Space Launch System will serve as the primary launch vehicle for Orion, while commercial launch vehicles are planned for use to launch various other elements of the campaign. NASA requested $1.6 billion in additional funding for Artemis for fiscal year 2020, and full funding has yet to be approved by Congress.
