This week’s image is from the Wide-Field Imager for Solar Probe (WISPR) aboard NASA’s Parker Solar Probe, which was launched in 2018 to observe the Sun. It shows the solar winds in the Sun’s outer atmosphere, or corona. The probe was about 3.8 million miles away from the Sun’s surface.

Here is a little more from NASA regarding the image:

The new WISPR images reveal the corona and solar wind, a constant stream of electrically charged particles from the Sun that rage across the solar system. The solar wind expands throughout of the solar system with wide-ranging effects. Together with outbursts of material and magnetic currents from the Sun, it helps generate auroras, strip planetary atmospheres, and induce electric currents that can overwhelm power grids and affect communications at Earth. Understanding the impact of solar wind starts with understanding its origins at the Sun.

The WISPR images give scientists a closer look at what happens to the solar wind shortly after it is released from the corona. The images show the important boundary where the Sun’s magnetic field direction switches from northward to southward, called the heliospheric current sheet. It also captures the collision of multiple coronal mass ejections, or CMEs — large outbursts of charged particles that are a key driver of space weather — for the first time in high resolution.

A Day in Astronomy: China Launches a Puppy into Orbit

On this day in 1966, China launched a male puppy named Xiao Bao (meaning Little Leopard) into space. He was used to test the effects of space and was safely recovered after the flight.

Thirteen days later a female puppy named Shan Shan (meaning Coral) was also launched into space. She too was safely recovered.

This is a much better tale than that of Laika, the dog that the USSR sent into orbit in 1957. As stray dog from the streets of Moscow, she only lasted a few hours after the launch, eventually dying of hyperthermia.

The Recently Created iSpace Crater Has Been Spotted

It doesn’t look like much, but NASA’s Lunar Reconnaissance Orbiter recently spotted the small crater made by the crashed ispace lunar lander named Resilience. The Japanese lander crashed on the Moon’s surface earlier this month after the company’s second try at a lunar landing.

The Moon is littered with debris and pockmarks from various successful and failed missions. The Apollo crew alone left enormous amounts of trash, debris, and space equipment scattered around the Moon. The Russians also left quite a bit of space equipment on the Moon many years ago, as well as its most recent Luna-25 mission, which crash-landed.

We can only hope that the Artemis mission will soon enough be adding to the equipment on the Moon without the drama of crash landings.

The European Space Agency is Staying Busy with Sunshine

While NASA is going crazy over budget cuts, the European Space Agency (ESA) is focused on new images from the Solar Orbiter spacecraft showing the sun’s south pole from a distance of about 40 million miles (shown above).

Launched in February 2020, Solar Orbiter is an ESA-led cooperative mission with NASA designed to answer a number of questions:

  • What drives the Sun’s 11-year cycle of rising and subsiding magnetic activity?
  • What heats up the upper layer of its atmosphere, the corona, to millions of degrees Celsius?
  • How does solar wind form, and what accelerates it to speeds of hundreds of kilometres per second?
  • How does it all affect our planet?

Professor Carole Mundell, ESA’s Director of Science, stated:

Today we reveal humankind’s first-ever views of the Sun’s pole…The Sun is our nearest star, giver of life and potential disruptor of modern space and ground power systems, so it is imperative that we understand how it works and learn to predict its behaviour. These new unique views from our Solar Orbiter mission are the beginning of a new era of solar science.

We all need a diversion from the ongoing budget news, so it is good to read about ongoing science and a successful mission.

Space Quote: Japanese Lunar Lander Fails a Second Time

“Given that there is currently no prospect of a successful lunar landing, our top priority is to swiftly analyze the telemetry data we have obtained thus far and work diligently to identify the cause.”

-Statement by Takeshi Hakamada, CEO and founder of Japan’s private space company ispace, in a press release following the failure of the company’s second lunar lander mission to the Moon. The company noted that the lander experienced a “hard landing” when it failed to sufficiently decrease its speed on approach. The mission started back in January when a SpaceX Falcon 9 rocket carried both this mission as well as Firefly Aerospace’s Blue Ghost, which had a successful landing on the lunar surface. The ispace lander was named Resilience – something it will need more of to stay in the space race.
