“Because of the Moon’s lack of water, atmosphere, and tectonic plates, there is little erosion, and craters are found that exceed two billion years in age. The age of large craters is determined by the number of smaller craters contained within it, older craters generally accumulating more small, contained craters.
The smallest craters found have been microscopic in size, found in rocks returned to Earth from the Moon. The largest crater called such is about 290 kilometres (181 mi) across in diameter, located near the lunar South Pole. However, it is believed that many of the lunar maria were formed by giant impacts, with the resulting depression filled by upwelling lava.”
“The more we fly the better we get. Safety and reliability are paramount. Our rigorous test program with New Shepard is putting the vehicle through the paces. We have successfully completed several crew capsule escape tests showing that our astronauts will be safe in any phase of flight. In addition to our test program, our payloads program is driving more flights of the system as we iterate on operations and technology in preparation for human spaceflight. All the learnings from the New Shepard program are being flowed into New Glenn development as we scale up our capabilities to serve the orbital market.”
“The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense. NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the “big five” U.S. intelligence agencies. The NRO is headquartered in unincorporated Fairfax County, Virginia, 2 miles (3.2 km) south of Washington Dulles International Airport.
It designs, builds, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA.”
“United Launch Alliance (ULA) is a provider of spacecraft launch services to the United States government. It was formed as a joint venture between Lockheed Martin Space Systems and Boeing Defense, Space & Security in December 2006 by combining the teams at the two companies. U.S. government launch customers include the Department of Defense and NASA, as well as other organizations. With ULA, Lockheed and Boeing held a monopoly on military launches for more than a decade until the US Air Force awarded a GPS satellite contract to SpaceX in 2016.
ULA provides launch services using two expendable launch systems – Delta IV and Atlas V. The Atlas and Delta launch system families have been used for more than 50 years to carry a variety of payloads including weather, telecommunications and national security satellites, as well as deep space and interplanetary exploration missions in support of scientific research. ULA also provides launch services for non-government satellites: Lockheed Martin retains the rights to market Atlas commercially.
Beginning in October 2014, ULA announced that they intended to undertake a substantial restructuring of the company, its products and processes, in the coming years in order to decrease launch costs. ULA is planning on building a new rocket that will be a successor to the Atlas V, using a new rocket engine on the first stage. In April 2015, they unveiled the new vehicle as the Vulcan, with the first flight of a new first stage planned for no earlier than 2020.”
“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.”
