The first and the last images of NASA’s Opportunity rover from the Martian surface. The first photo (on the left) was acquired on Sol 1 (at approximately 14:58:27 Mars local solar time on January 25, 2004). The last photo (on the right) was taken on Sol 5111 (on June 10, 2018 ), before the rover entered hibernation due to a huge dust storm.

In this episode of NASA Explorers (Season 1 Episode 7), the scientists go back in time – by going underground. In the Arctic, a frozen layer of soil – permafrost, the “permanently” frozen earth – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane – two harmful greenhouse gases which contribute to global warming.

If we want to colonize Mars in the future, it would be better for us to terraform the planet, in order to make the colonization process safer and sustainable. But, terraforming Mars will be a real challenge for humanity.

NASA’s InSight lander takes a selfie – this is what it looks like on Mars (InSight is the abbreviation for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport). With its solar panels deployed, InSight is about the size of a small bus.

Ignorance is a very, very bad thing. Last week, as North America suffering from extreme cold weather because of a phenomenon called “polar vortex“, Jim Hoft, founder of the American far-right news and opinion website The Gateway Pundit has tweeted that: “It’s a bit cold outside this morning in middle America… Aren’t you glad you aren’t heating your home with a solar panel like nitwit socialist @AOC is demanding?” (@AOC is the American politician and activist Alexandria Ocasio-Cortez here.) What Jim Hoft says is flat-out wrong. Solar panels DO work in the cold. They work by absorbing LIGHT from the sun, not heat.

Here is a quick summary of the Earth’s snow cover between March 2000 and December 2018. These snow cover maps are made from observations collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.

According to research published in the journal Earth and Planetary Science Letters, Earth’s oldest rock (which is 4.1 billion years old) has been found in an Apollo 14 sample from the Moon. If confirmed, it’s an amazing discovery.

As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.
