NASA’s InSight spacecraft is on track for a soft touchdown on the surface of the Red Planet on November 26, scientists monitoring the health and trajectory of the lander have said.

InSight will hit the top of the Martian atmosphere at 19,800 kilometres per hour (kph) and slow down to eight kph — about human jogging speed — before its three legs touch down on Martian soil.

That extreme deceleration has to happen in just under seven minutes.

“There’s a reason engineers call landing on Mars ‘seven minutes of terror,'” Rob Grover, InSight’s entry, descent and landing (EDL) lead, based at NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement.

“We can’t joystick the landing, so we have to rely on the commands we pre-programme into the spacecraft. We’ve spent years testing our plans, learning from other Mars landings and studying all the conditions Mars can throw at us.

“And we’re going to stay vigilant till InSight settles into its home in the Elysium Planitia region,” Grover said.

Launched on May 5, Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander marks NASA’s first Mars landing since the Curiosity rover in 2012.

The landing will kick off a two-year mission in which InSight will become the first spacecraft to study Mars’ deep interior.

Its data also will help scientists understand the formation of all rocky worlds, including our own.

About 80 live viewing events for the public to watch the InSight landing will take place around the world. It will be at 3 p.m. EST meaning 1.30 a.m. in India on November 27.

People from around the world will be able to watch the event live on NASA Television, the agency’s website and social media platforms, including on YouTube.

“Landing on Mars is exciting, but scientists are looking forward to the time after InSight lands,” said Lori Glaze, Acting Director of the Planetary Science Division at NASA headquarters. (IANS)

NASA and SpaceX postponed historic launch of two astronauts to space from NASA’s Kennedy Space Center in Florida on Wednesday due to bad weather.

“Due to the weather conditions, the launch is scrubbing,” NASA tweeted, Xinhua reported.

SpaceX said the launch was delayed due to unfavourable weather in the flight path.

NASA is seeking US citizens for an eight-month study on social isolation in preparation for missions to Mars and the moon.

The international space agency is preparing for its next spaceflight simulation study and is seeking healthy participants to live together with a small crew in isolation for eight months in Moscow, Russia.

Participants will be staying in a lab located in Moscow, and they will experience environmental aspects similar to those astronauts are expected to experience on future missions to Mars that will have crew members from different nations.

NASA is looking for highly motivated and healthy individuals between the ages of 30 and 55 who are fluent in both English and Russian. They must also have an MS., PhD, MD. or have completed military officer training.

The space agency will consider other participants with a bachelor’s degree and other qualifications such as military or professional experience.

They will study the psychological and physiological effects astronauts are likely to face as a result of isolation on long missions.

According to NASA, participants will experience environmental aspects similar to those astronauts are expected to experience on future missions to Mars.

A small international crew will live together in isolation for eight months conducting scientific research, using virtual reality and performing robotic operations among a number of other tasks during the lunar mission.

The research is being done to study the effects of isolation and confinement as participants work to complete simulated space missions.

Results from ground-based missions like this help NASA prepare for the real-life challenges of space exploration and provide important scientific data to solve some of these problems and to develop countermeasures.

Participants will be compensated, and there are varying levels of pay depending on whether you’re associated with NASA.

This study builds on a four-month study conducted in 2019. The SIRIUS-19 analog mission had six participants — two US citizens and four Russians — isolated in a metal habitat that acted as their spacecraft, lunar lander and home. (IANS)

Scientists to Probe Jupiter’s Violent Storms, Lightning Strikes

Scientists from various organisations probe Jupiter's violent Storms and lightning strikes

NASA’s Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms on the giant planet Jupiter.

The images, part of a multi-year joint programme, revealed that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid.

The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud colour variations.

Three years of imaging observations using the international Gemini Observatory have probed deep into Jupiter’s cloud tops. The ultra-sharp Gemini infrared images complement optical and ultraviolet observations by Hubble and radio observations by the Juno spacecraft to reveal new secrets about the giant planet.

“The Gemini data were critical because they allowed us to probe deeply into Jupiter’s clouds on a regular schedule,” said Michael Wong of University of California, Berkeley.

“We used a very powerful technique called lucky imaging,” added Wong.

With lucky imaging, a large number of very short exposure images are obtained and only the sharpest images, when the Earth’s atmosphere is briefly stable, are used. The result in this case is some of the sharpest infrared images of Jupiter ever obtained from the ground.

According to Wong, “These images rival the view from space.”

Gemini North’s Near Infrared Imager (NIRI) allows astronomers to peer deep into Jupiter’s mighty storms, since the longer wavelength infrared light can pass through the thin haze but is obscured by thicker clouds high in Jupiter’s atmosphere.

This creates a “jack-o-lantern”-like effect in the images where the warm, deep layers of Jupiter’s atmosphere glow through gaps in the planet’s thick cloud cover.

The detailed, multiwavelength imaging of Jupiter by Geminiand Hubble has, over the past three years, proven crucial to contextualizing the observations by the Juno orbiter, and to understanding Jupiter’s wind patterns, atmospheric waves, and cyclones.

The two telescopes, together with Juno, can observe Jupiter’s atmosphere as a system of winds, gases, heat, and weather phenomena, providing coverage and insight not unlike the network of weather satellites meteorologists use to observe Earth.

Because the Hubble and Gemini observations are so important for interpreting Juno data, Wong and his colleagues are making all of the processed data easily accessible to other researchers through the Mikulski Archives for Space Telescopes (MAST) at the Space Telescope Science Institute in Baltimore, Maryland.
