US shutdown delays space missions but NASA not grounded: Report,

NASA’s Ralph, one of the most well-travelled scientific instrument, is set to explore Jupiter’s Trojan asteroids aboard the Lucy spacecraft in 2021, the US space agency said.

Ralph has made many discoveries since it first launched aboard the New Horizons spacecraft in 2006. Given a name and not an acronym, Ralph enables the study of the composition and atmospheres of celestial objects.


In 2021, the Lucy spacecraft will carry a near-twin of Ralph, called L’Ralph (“Lucy Ralph”), to investigate Jupiter’s Trojan asteroids, which are remnants from the early days of the solar system, NASA said in a statement on Wednesday.

The L’Ralph instrument suite will study this diverse group of bodies. Lucy will fly by six Trojans and one Main Belt asteroid, more than any other previous asteroid mission.

L’Ralph will detect the Trojan asteroids’ chemical fingerprints, the statement said.

L’Ralph allows scientists to interpret data provided by the Sun’s reflected light that are the fingerprints of different elements and compounds.

These data could provide clues about how organic molecules form in primitive bodies, a process that might also have led to the emergence of life on Earth.

L’Ralph needs to have many capabilities in a small, light body structure to keep the spacecraft efficient and the mission productive.

Its instrument suite contains the Multi-spectral Visible Imaging Camera (MVIC) and the Linear Etalon Imaging Spectral Array (LEISA), both of which are fed by the same optics, meaning that Ralph can observe both visible and infrared wavelengths.

These dual capabilities are what makes Ralph and its cousin L’Ralph so special, according to Dennis Reuter, the instrument principal investigator for L’Ralph.

“Most instruments can image visible or infrared wavelengths, but L’Ralph can do both,” said Reuter.

Compared to the Ralph that flies with New Horizons, Lucy’s L’Ralph has enhanced technology. It can detect a broader spectrum of electromagnetic radiation, it has a moving mirror that reflects light into L’Ralph instead of requiring movements of the entire spacecraft.

Ralph’s infrared detectors are 2,000 pixels square, compared to New Horizons Ralph’s 256 by 256, allowing for images with more detail. (IANS)

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment.

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment. While everyone is making their big fat Indian wedding dreams come true, they are also adding their carbon footprint and undue energy consumption. Modern couples are now looking for ways to have a wedding with a sustainably conscious mindset. It's become about incorporating less waste, locally sourced and seasonal food, natural materials over the use of plastic. Mindful wedding planning and decor includes the use of recycled paper and goods along with eco-friendly venue needs. Check out this quick guide to achieve a sustainably conscious wedding without compromising on luxury:

Choose locally sourced material to uplift artisans
Sustainable can be luxurious too, incorporate some native flavour into the decor and theme. With the use of locally sourced materials and local artisans coming into play, the wedding instantly becomes sustainable. Include the work of local vendors ensure minimal packaging requirements, thus saving on unnecessary plastic and lamination. It also decreases the need for transporting elements from other cities and hence lowers the carbon footprint. For instance, at one of our weddings, we made use of sand art for a setup in Jodhpur. This helped promote local work while also being environmentally friendly with zero wastage of other materials. In another instance from Rajasthan, the traditional glass-blown technique was used to build decor items while giving a cultural touch to the destination wedding.

The health department officials also said that as the state has almost exhausted its quota of vaccines, there would not be any vaccines on Monday. Regular vaccination will resume after the vaccine supplies arrive from New Delhi, officials said. The state health department had expected to vaccinate 15 lakh people on Sunday in 18,824 centres spread across primary health centres, anganwadis, noon meal centres, government hospitals, schools and some auditoriums.
