Challenging Ourselves to Create the Next Generation of Lunar Explorers by Staff Writers Washington DC (SPX) Apr 16, 2019
Space exploration brings humanity some of its greatest challenges and opportunities. We faced this hard fact on April 11 when the Beresheet spacecraft developed by Israel's SpaceIL failed to successfully land on the Moon's surface. While the Beresheet spacecraft can claim many accomplishments, including being the first privately funded lunar spacecraft, we can learn many things from its failures. These are lessons we, too, must consider as NASA tries to conquer similar challenges as we move forward to the Moon with commercial and international partners. NASA will use new landers and robots ahead of humans to explore the Moon. By the time we land astronauts on the lunar South Pole in 2024, many commercial deliveries to the Moon already will be complete. Other nations continue to work on their own lunar landing plans, and we'll also benefit from those efforts. Early deliveries in NASA's Commercial Lunar Payload Services (CLPS) program will carry science experiments and technology demonstrations to the Moon and help improve designs for new human lunar landers. This work will help us retire risk, take advantage of the Moon's resources, and prepare for eventual missions to Mars. The first CLPS task order was given in March, and nine companies are now bidding on the first delivery opportunity and picking from the suite of tools they want to deliver to the lunar surface. At least one award is expected in May. "We're looking at speed to get us back to the Moon," said NASA Administrator Jim Bridenstine. "We want fast and regular robotic deliveries ahead of an accelerated human return by 2024. Then, we want to establish sustainable human surface missions by 2028." Experience shows that not every early robotic delivery attempt will be successful. "We want to fly CLPS this year and are willing to take risks to learn," said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "We want to get new robotic precursors to the Moon to study as much as possible before we send astronauts to the surface." Since first landing on the Moon with Surveyor in 1966, NASA has faced both success and failure, and both will continue to be a part of the process. America is only one of three nations to successfully land robots on the Moon, and remains the only one to send humans to the surface. That will change with this generation. And commercial and international partnerships are essential to the agency's efforts to return to the Moon. "A sustainable return to the Moon means we have the ability to go back and forth from the surface - and land anywhere on the surface - at any time," said Bridenstine. "We need partners to do that. We're not just doing this for NASA, we're exploring for all of us." Space is hard, but the space community is an ever-learning network built to grow from both wins and losses.
Lunar gravity 600 kilometres above Earth Bremen, Germany (SPX) Apr 12, 2019 The compact German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) Eu:CROPIS satellite is now rotating in space at a rate of 17.5 revolutions per minute, generating a gravitational force in its interior similar to that found on the Moon. After its launch on 3 December 2018, DLR engineers successfully tested and commanded the spacecraft. The experiments were then put into operation on 5 December. As the upload of updated software for the two greenhouses inside the spacecraft cause ... read more
