A group of scientists has discovered two unusually red objects in the asteroid belt between Jupiter and Mars, and they may have originated from farther in the solar system. These objects — called Pompeja and Justitia — are redder than the reddest known objects in the asteroid belt and may have migrated to the area from beyond Neptune.
If that's true, then they could provide insight into the chaos of the early solar system and into how the solar system as we know it today came to be. As The New York Times points out, most objects in the inner solar system tend to reflect blue light, because they're devoid of or have very little organic materials.
Objects from the outer solar system such as the Kuiper belt, however, tend to be redder. Scientists found evidence that an area on Mars called Arabia Terra had thousands of "super eruptions" over a million-year period. Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region. Data received late Sept. The rover will abrade a rock this week, allowing scientists and engineers to decide whether that target would withstand its powerful drill.
Drought is a complicated problem that requires lots of data. Satellites from NASA and its partners help collect that data. Drought Makes its Home on the Range.

Grades 6 - 8. Do you agree with this alignment? Thanks for your feedback! Alignment agreement: Thanks for your feedback! View aligned curriculum. Students are introduced to the planet Mars.
They begin by discussing the location and size of Mars relative to Earth, as well many interesting facts about this "red planet. Students explore the outermost planets of our solar system: Saturn, Uranus and Neptune. They also learn about characteristics of Pluto and its interactions with Neptune. Students learn a little about the history of space travel as well as the different technologies that engineers develop to make spa Students explore Mercury and Venus, the first and second planets nearest the Sun.
They learn about the planets' characteristics, including their differences from Earth. Students also learn how engineers are involved in the study of planets by designing equipment and spacecraft to go where it is too Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system.
In accompanying activities, they explore how ground-based tracking and onboard measurements are performed. Past Mercury, Venus and the Earth, what are the next two planets from the Sun in our solar system?
You've got it! Mars and Jupiter are the fourth and fifth planets from the Sun. Optional: Show students an image of all the planets in our solar system, so they understand their relative position from the Sun; see the attached Solar System Map Visual Aid. Between them is the asteroid belt. Let's make a list on the board of facts about these two planets.
First Mars is the fourth planet from the Sun. Have any of you seen Mars in the night sky? Well, Mars is one of the brightest objects in the night sky. Sometimes it looks red. It is actually called the "red planet" because of its red soil. If you were on Mars, its sky would look hazy and red not blue.
Even though Mars is a red and rocky planet that is cold and deserted, it is the planet that is the most like our own Earth. Mars may be the next planet that humans could go to live on, but life on Mars would be a lot different from here. While Mars has seasons like Earth, they range from very cold to even colder. In its summer, Mars barely gets above freezing! Also, the atmosphere on Mars is poisonous to humans.
You would need to wear a protective spacesuit to breathe on Mars. Engineers design, experiment and test prototypes of Mars rovers in an oversized sandbox before they are ready to be sent to the planet. Now let's talk about Jupiter. Jupiter is the fifth planet from the Sun and the largest of all the planets in our solar system. According to NASA, it is twice as large as all of the other planets combined!
Jupiter has more than 60 moons. Jupiter is called a "gas giant" because it is made up of mainly hydrogen and helium. In fact, Jupiter has no solid surfaces. There is no place to stand on Jupiter. Also, Jupiter is under so much atmospheric pressure that a person trying to visit there would be crushed and melted instantly.
In fact, the Galileo probe, sent to Jupiter in , only lasted 59 minutes in Jupiter's atmosphere before it was crushed. Have you ever looked at Jupiter through a telescope?
If you have, you may have seen the Giant Red Spot. This is one characteristic that you can see on Jupiter. What is the spot? It is actually a huge storm that's about the size of three Earths!
