SpaceX Dragon – an unreal shot

On May 4, 2019, the American space company SpaceX launched its 17th contracted cargo resupply mission (SpaceX CRS17, also known as SpX-17) to the International Space Station (ISS) aboard a Falcon 9 rocket, carrying 2,482 kg (5,472 lb) of cargo. You can watch the launch at 15:00 in the video at the end of this post.

Following the stage separation, Falcon 9’s first stage landed successfully on the Of Course I Still Love You droneship that was stationed in the Atlantic Ocean (the landing begins at 23:00 in the video below, at the end of this post).

Two days after the launch, the SpaceX Dragon docked at the Harmony module. There it remained for about one month before returning to Earth with a splashdown in the Pacific Ocean on June 3.

While attached to the station, the crew of the orbiting laboratory took a lot of photos of the spacecraft. One of the photos (below), showing the Dragon craft moments before being released from the Canadarm2 robotic arm, was unreal.

Earth’s atmosphere is leaking and NASA is sending rockets to understand how

Earth’s atmosphere is leaking: around 90 tonnes of material escapes and streams out into space from our planet’s upper atmosphere every single day.

To understand this escape, NASA launches rockets into space. The space agency also sends scientists to a tiny Arctic town named Ny-Ålesund (English: New Alesund) on the island of Spitsbergen in Svalbard, Norway. Because understanding this atmospheric escape on Earth can benefit us in many ways – from predicting which exoplanets might be habitable, to piecing together how Mars became the desolate, exposed planet it is today.

Martian Scenic Overlook by Curiosity

An amazing video by NASA titled “Curiosity at Martian Scenic Overlook”. Curiosity Project Scientist Ashwin Vasavada gives a descriptive tour of the Mars rover’s view in Gale Crater which is 154 kilometers (96 miles) in diameter and estimated to be about 3.5-3.8 billion years old. It is created by an impactor. The crater is also probably a dry lake (once filled with water – probably billions of years ago).

Here’s why Mars is cold despite having an atmosphere of mostly carbon dioxide

Mars, often referred to as the Red Planet, boasts an atmosphere dominated by carbon dioxide, a gas typically associated with warmth-inducing greenhouse effects on Earth. Yet, anyone expecting balmy temperatures on Mars would be in for a chilly surprise. Despite its CO₂-rich atmosphere, Mars remains an icy desert with temperatures often plummeting far below freezing. The paradoxical nature of a cold planet blanketed by a gas known for trapping heat sparks curiosity and demands an explanation. In this article, we’ll delve into the multifaceted reasons behind Mars’ frigid climate, revealing the intriguing interplay of astrophysical, geological, and atmospheric factors that keep our neighboring planet cold.
