NASA looks at returning to Venus

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Sue Smrekar really wants to go back to Venus. In her office at NASA’s Jet Propulsion Laboratory in Pasadena, California, the planetary scientist displays a 30-year-old image of Venus’ surface taken by the Magellan spacecraft, a reminder of how much time has passed since an American mission orbited the planet.

The image reveals a hellish landscape: a young surface with more volcanoes than any other body in the solar system, gigantic rifts, towering mountain belts and temperatures hot enough to melt lead.

Venus hides a wealth of information that could help us better understand Earth and exoplanets. NASA's JPL is designing mission concepts to survive the planet's extreme temperatures and atmospheric pressure. This image is a composite of data from NASA's Magellan spacecraft and Pioneer Venus Orbiter. (NASA/JPL-Caltech)

NASA research shows Neptune Moons orbits connected to avoid each other

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says even by the wild standards of the outer solar system, the strange orbits that carry Neptune’s two innermost moons are unprecedented, according to newly published research.

Orbital dynamics experts are calling it a “dance of avoidance” performed by the tiny moons Naiad and Thalassa. The two are true partners, orbiting only about 1,150 miles (1,850 kilometers) apart. But they never get that close to each other; Naiad’s orbit is tilted and perfectly timed. Every time it passes the slower-moving Thalassa, the two are about 2,200 miles (3,540 kilometers) apart.

NASA’s Rocket to the Moon, What Is the Exploration Upper Stage?

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Space Launch System (SLS) rocket delivers propulsion in stages to send NASA’s Orion spacecraft and heavy cargo to the Moon for the Artemis lunar missions.

At liftoff, the core stage and twin solid rocket boosters fire to propel the rocket off the launch pad send it into orbit. Once in orbit, the upper stage provides the in-space propulsion to set the spacecraft on a precise trajectory.

NASA launches Ionospheric Connection Explorer (ICON) spacecraft

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After a successful Thursday night, October 10th, 2019 launch, NASA’s Ionospheric Connection Explorer (ICON) spacecraft is in orbit for a first-of-its-kind mission to study a region of space where changes can disrupt communications and satellite orbits, and even increase radiation risks to astronauts.

A Northrop Grumman Stargazer L-1011 aircraft took off at 7:31pm CDT from Cape Canaveral Air Force Station in Florida carrying ICON, on a Northrop Grumman Pegasus XL rocket, to launch altitude of about 39,000 feet.

Northrop Grumman’s L-1011 aircraft, Stargazer, prepares for takeoff at the Cape Canaveral Air Force Station Skid Strip in Florida on Oct. 10, 2019. Attached beneath the aircraft is the company’s Pegasus XL rocket, carrying NASA’s Ionospheric Connection Explorer (ICON). (NASA)

NASA’s original Artemis Mission studied interaction of Moon, Sun

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – By 2024, NASA will land astronauts, including the first woman and next man, on the Moon as part of the Artemis lunar exploration program. This won’t be the first time NASA takes the name Artemis to the Moon though.

Two robotic spacecraft orbiting the Moon today were initially known as ARTEMIS — short for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun. Since 2011, these spacecraft have been sending scientists valuable information about the lunar environment, and laying groundwork critical to returning humans to the Moon.

NASA looks to understand Asthma from Space

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA says help may be on the way for the millions of people around the world who suffer from asthma. Pioneering research in orbit is opening new avenues to understanding what goes wrong in patients with airway inflammation.

The results have contributed to the development of quick lung tests for an improved quality of life––both on Earth and in space. With each lungful of air, our bodies absorb oxygen and exhale waste products. In people with asthma, inflammation in the lung adds nitric oxide to exhaled air. Doctors measure the amount of nitric oxide exhaled by patients to help diagnose inflamed lungs and asthma.

NASA’s Orion’s Service Module passes Propulsion Test

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In order to send astronauts to the Moon for Artemis missions, NASA is working on building a new system that includes tests to make sure the Orion spacecraft is prepared to safely carry crew on an alternate mission profile in the face of unexpected problems.

That capability was most recently demonstrated with a successful, continuous 12-minute firing of Orion’s propulsion system that simulated a possible alternate mission scenario.

NASA announces One of the Two Van Allen Probe Spacecraft shutdown

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA reports that on July 19th, 2019, mission operators sent a shutdown command to one of two Van Allen Probes spacecraft at 12:27pm CT, known as spacecraft B, from the Johns Hopkins University Applied Physics Laboratory, or APL, in Laurel, Maryland.

As expected, following final de-orbit maneuvers in February of this year, the spacecraft has used its remaining propellant to keep its solar panels pointed at the Sun and is now out of fuel.

NASA began Journey to the Moon 50 Years Ago

 

NASA - National Aeronautics and Space AdministrationHouston, TX – Around one million people gathered on the beaches of central Florida to witness first-hand the launch of NASA’s Apollo 11, while more than 500 million people around the world watched the event live on television.

Officially named as a crew just six months earlier, Commander Neil A. Armstrong, Lunar Module Pilot (LMP) Edwin E. “Buzz” Aldrin, and Command Module Pilot (CMP) Michael Collins were prepared to undertake the historic mission.
