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)

Doris Lessing who won a Nobel Prize in Literature

London (CNN)- At five o'clock in the morning, the esteemed 86-year-old astrophysicist Jim Peebles was woken suddenly by the telephone ringing.

"In previous experience, the only phone calls at that time of night are bad news," he said. This one was great news. "The opening sentence from the caller was: 'The Nobel committee has voted to award you the Nobel Prize in Physics. Do you accept?'" Peebles recalled. The wording threw him. Who wouldn't accept a Nobel Prize? "You know the Bob Dylan fiasco?" he said during a phone interview with CNN. "That might have put the wind up them."The "fiasco" Peebles mentions refers to the 2016 Nobel Prize in Literature, which was controversially given to an utterly unimpressed Dylan.Aside from being ever-presents on college campuses in the 1960s, little connects Peebles, an expert in theoretical cosmology, with Dylan. But one of the starkest contrasts might lie in their reactions to winning a Nobel -- and the songwriter is far from the only laureate whose crowning turned out to be an awkward affair.

The five committees are notoriously secretive, fiercely shielding their choices from the outside world -- including the laureates themselves, who are told of their victories just minutes before they are announced to the public.

Sindoor implies the longevity of a woman's marriage to her husband in the Hindu tradition

Married Hindu women are recognised by a red streak of vermillion in the middle of their foreheads. This is traditionally called 'sindoor', which is derived from the Sanskrit word sindura, meaning 'red lead.'. Sindoor is traditionally powdered turmeric and lime, sometimes red saffron, or red sandalwood. It is also called vermilion, or Kumkum.
