“The Mars 2020 rover mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The Mars 2020 mission addresses high-priority science goals for Mars exploration, including key questions about the potential for life on Mars. The mission takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a “cache” on the surface of Mars. A future mission could potentially return these samples to Earth. That would help scientists study the samples in laboratories with special room-sized equipment that would be too large to take to Mars. The mission also provides opportunities to gather knowledge and demonstrate technologies that address the challenges of future human expeditions to Mars. These include testing a method for producing oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing weather, dust, and other potential environmental conditions that could affect future astronauts living and working on Mars.”

“Rocket Lab is a private American aerospace manufacturer and smallsat launcher with a wholly owned New Zealand subsidiary. It has developed a suborbital sounding rocket named Ä€tea and currently operates a lightweight orbital rocket known as Electron, which provides dedicated launches for smallsats and CubeSats.

The Electron test program began in May 2017, with commercial flights announced by the company to occur at a price listed in early 2018 as US$5.7 million. Launching from Mahia Peninsula, New Zealand, the rocket’s test flights took place on 25 May 2017 and 21 January 2018, while its first commercial flight took place on 11 November 2018. On December 16 Rocket Lab launched their first mission for NASA; the rocket contained 13 Satellites for the ELaNa-19 mission.”

“101955 Bennu (provisional designation 1999 RQ36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table with the second-highest cumulative rating on the Palermo Technical Impact Hazard Scale. It has a cumulative 1-in-2,700 chance of impacting Earth between 2175 and 2199. Its name references Bennu, the ancient Egyptian mythological bird associated with the Sun, creation, and rebirth.

101955 Bennu has a mean diameter of approximately 492 m (1,614 ft; 0.306 mi) and has been observed extensively with the Arecibo Observatory planetary radar and the Goldstone Deep Space Network.

Bennu is the target of the OSIRIS-REx mission which is intended to return samples to Earth in 2023 for further study. On 3 December 2018, the OSIRIS-REx spacecraft arrived at Bennu after a two-year journey. Before attempting to obtain a sample from the asteroid, it will map out Bennu’s surface in detail and orbit the asteroid to calculate its mass.”

“We completed the second qualification test for the launch abort motor for NASA’s Orion Spacecraft. The motor fired for 5 seconds with a force of just under 370,000 pounds and will be used to pull the crewed capsule away from NASA’s Space Launch System in the event of an emergency on the launch pad or during ascent. The next major milestone for the motor will be the Ascent Abort-2 Flight Test (AA-2) that will take place in 2019.”

“The Space Launch System (SLS) is an American Space Shuttle-derived super heavy-lift expendable launch vehicle. It is part of NASA’s deep space exploration plans including a crewed mission to Mars. SLS follows the cancellation of the Constellation program, and is to replace the retired Space Shuttle. The NASA Authorization Act of 2010 envisions the transformation of the Constellation program’s Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo, similar to the Ares IV concept. The SLS is to be the most powerful rocket ever built with a total thrust greater than that of the Saturn V, although Saturn V could carry a greater payload mass.

The SLS launch vehicle is to be upgraded over time with more powerful versions. Its initial Block 1 version is to lift a payload of 95 metric tons to low Earth orbit (LEO), which will be increased with the debut of Block 1B and the Exploration Upper Stage. Block 2 will replace the initial Shuttle-derived boosters with advanced boosters and is planned to have a LEO capability of more than 130 metric tons to meet the congressional requirement. These upgrades will allow the SLS to lift astronauts and hardware to destinations beyond LEO: on a circumlunar trajectory as part of Exploration Mission 1 & 2 with Block 1; to deliver elements of the Lunar Orbital Platform-Gateway (LOP-G) with Block 1B; and to Mars with Block 2. The SLS will launch the Orion Crew and Service Module and may support trips to the International Space Station if necessary. SLS will use the ground operations and launch facilities at NASA’s Kennedy Space Center, Florida.”

“Scientists from NASA Goddard have discovered that not only are Saturn’s rings younger than previously thought, but also that the rings are actually disappearing at a rapid pace through a process called ring rain.”
