Next month, nearly half a century since the US's last spacecraft landed on the Moon, it is expected that NASA will announce plans to return. But the agency will only be on its way. Instead of discovering plans for their spacecraft, NASA will call private companies to pay for the transmission of science on explosives to the Moon on small robotic landers.
Within the program called Commercial Lunar Paiload Services (CLPS), NASA would buy space on a pair launch yearly, starting in 2021. The effort is similar to an agency program that has paid to private space companies such as Elon Musk SpaceKs to deliver cargo International Space Station (ISS). "This is a new way of doing business," says Sarah Noble, a planetary scientist at NASA in Washington, DC, who leads NASA's scientific side for lunar plans.
The scientists are moving for a ride. "It really feels like the future of lunar exploration," says Erica Javin, a planetary scientist at the Smithsonian Institute's National Museum of Natural History in Washington, She and others present at the annual meeting of the Lunar Research Group in Columbia, Maryland, last week were eager to show NASA why their little experiments would be worthy of highways at the docks.
Several companies, including Astrobot, Moon Ekpress and iSpace, are on the market for the commercial month. Buying a drive to the Moon from a launcher such as Rocket Lab, every company hopes to become a carrier for other companies looking for a rocket propellant moon or collect stones for sale for study. But the contract with NASA is a real reward. Moon Ekpress, for example, designed the MKS-1, lander roughly the size and shape Star WarsR2-D2. But, "We will not pull the trigger until we find out that we have a CLPS award," says Robert Roberts CEO Robert Roberts in Cape Canaveral, Florida.
Companies selected for CLPS have to deliver at least 10 kilograms of payload by the end of 2021, says NASA. It's wider to find instruments that are ready to fly. "What are you sitting on the shelf now that you can immediately throw it on the mission?" Noble says. "We are looking for spare flights, engineering models, study projects, it's a little weird call for us." The agency plans to pay up to $ 36 million to adapt eight to 12 existing scientific instruments to initial small supporters; by the middle of the next decade, the goal is to build a pipeline of instruments for larger supporters who could carry trenches.
The first small commercial fleet will reduce capacity alongside traditional NASA missions. Some will probably fail, as NASA's head of science, Thomas Zurbuchen, has repeatedly warned. It will not survive the lunar night, 2 weeks when the surface temperature drops to -173 ° C. They may not be able to land at a particular location. But scientists are still excited to return cameras and other instruments to the surface of the Moon, says Clive Neal, a lunar scientist at Notre Dame University in South Bend, Indiana. "It's a great start."
NASA is still developing destinations for commercial supporters. Earlier this year, lunar scientists compiled a list of 16 locations that are key to testing the resulting Moon picture as being more volcanic and richer in water than it was meant to be. For example, four years ago, scientists who studied Ina Caldera, a collection of smooth, small volcanic piles on the Neo-Neo-Moon, noticed that it was relatively free from the crater. Observation has shown that instead of ending more than a billion years ago, vulcanism – a sign of inner heat – remained until several million years ago, ironing the landscape. If it is true – and some slow, finding – it would involve theories about how the moon and potentially rocky planets cool down over time.
On the Aristarchus plateau, 2 miles high, scientists want to study the rich volcanic ash deposits generated by explosive gas-eruptive eruptions, which is a rarity on the Moon. Thanks to its fine granularity, ash could also make an excellent human habitat block. Samples of Marius Hills, shield volcanoes that were likely to erupt in considerable time, could illuminate how the moon's consumption of water, carbon monoxide and other volatile matter evolved over time. A glimpse of permanently sintered craters at half-moon can confirm whether some of its waters are frozen there, says Brett Denevi, a planetary geologist at the Johns Hopkins University's Applied Physics Laboratory in Laurel, Mariland.
The first small lander only allows small steps toward these scientific goals. However, the agency could eventually support commercial robotic reverse missions, which Astrobot and Moon Ekpress are offered to offer. "We could say," I want 2 kilograms of lunar regolith from such a location, "says John Thornton, executive director of Astrobotics in Pittsburgh, Pennsylvania. Backlinks can help researchers with a long-standing goal: they give birth to old and young craters of the moon who dictate estimates age for surfaces over the Solar System.
NASA also wants to fly people back in the vicinity of the Moon – but in their spaceship. It builds Gatevai, a small outpost, that by 2024 the astronauts will be accommodated for several months simultaneously in volume under the pressure of one tenth of the size of the ISS. Gatevai, which NASA will cost at least $ 3 billion for the first few sections, would not orbit the Moon, but would follow a weekly loop around a distant gravitational point of balance – a bad advantage for lunar observations. "We are not 100% confident in our value for lunar science," says Ryan Watkins, a lunar scientist at the Institute of Planetary Science at St. Louis, Missouri. Noble admits that Gatevai can be more useful for studying the Sun or the rest of the universe.
Ben Bussei, NASA's chief researcher for human research, says the agency is trying to respond to the concerns of scientists. For example, the priority is equipping the cell with a robotic arm, necessary for mounting experiments on the exterior. And exploring the possibility of a space-capable spacecraft capable of transporting supporters, samples, and instruments between Gatevai and the low lunar orbit, says Bussei.
Above these lunar plans, fear is that they will change. Republicans in Congress have proposed the return of the month under former President George W. Bush, only that the administration of former President Barack Obama would emphasize a deep-space asteroid visit, as a springboard for Mars. So far, the Republican Congress has fully funded the Agency's monthly plans: Consumer Plans 2019 contain $ 500 million for Gatevai and more than $ 200 million for NASA's initials for beginners and scientists. Now, lunar scientists must transfer their support to newly founded democracies, Neal says. If NASA finances few small supporters and the program changes again, Deny adds: "It will be just another lost decade."
