मै दीवारों से बनी एक महल बस नहीं, जहाँ होते हो चर्चा, एक सदन बस नहीं, न कानून बनाने का एक केंद्र बस हु मै, मै हूँ इस देश की गौरव, दिशा देने वाली… हाँ मै ही थी जिसने कानून बनवाएं, मैंने ही आपके हक थे दिलवाए, मैंने ही थे आपके कर्त्तव्य भी बताये, और मेरे ही शोर ने अबतक देश है चलाएं… किन्तु खेद क़ी समय से नहीं रह सक़ी अछूती, दिशा देती थी जो सबको, आज खुद ही है भटकी, जिसे थे सुलझाने समस्या, आज झेल रही है समस्या, आज संशय में शायद, क्या मै हूँ देश बनाती? ये है मै ही थी, स्व पे गुमान करती थी, अपनों के त्याग पे मान करती थी, और में ही हु आज, खुद को दोषी कहती, अपने घरवालों को हूँ दागी कहती.. लड़ना घरवालों का कुछ नया नहीं था, पर बिकना रुपयों में क्या देश द्रोह से कम था? ताज्जुब नहीं की तब चौकीदार सोया था, शक हुआ यकीन कि अब वो भी बिका था… वो दौर कोई और था जब अपने भाग्य थी इठलाती, था मन में एक गुरूर कि मै ही देश चलाती, पर ये गौरव, गुमान क्षणिक ही रह गया, अपनों के स्वार्थ ने ये दिन दिखा दिया.. है निवेदन सबसे, मेरे सुनहरे दिन लौटा दो, जो देश एक कर सके, वो पटेल मुझे लौटा दो, सादगी हो शास्त्री सी जिसमें, अटल गुण संपन्न हो, बिना भेद जो देश चलायें उसी को सत्ता पे तुम बिठा दो.. #parliament #janpath #rashtrapatibhavan (at Parliament of India) https://www.instagram.com/p/BsLTtTTB3i6/?utm_source=ig_tumblr_share&igshid=yyrzn8gxwiiv

Cassini Mission: What’s Next?

It’s Friday, Sept. 15 and our Cassini mission has officially come to a spectacular end. The final signal from the spacecraft was received here on Earth at 7:55 a.m. EDT after a fateful plunge into Saturn’s atmosphere.

After losing contact with Earth, the spacecraft burned up like a meteor, becoming part of the planet itself.

Although bittersweet, Cassini’s triumphant end is the culmination of a nearly 20-year mission that overflowed with discoveries.

But, what happens now?

Mission Team and Data

Now that the spacecraft is gone, most of the team’s engineers are migrating to other planetary missions, where they will continue to contribute to the work we’re doing to explore our solar system and beyond.

Mission scientists will keep working for the coming years to ensure that we fully understand all of the data acquired during the mission’s Grand Finale. They will carefully calibrate and study all of this data so that it can be entered into the Planetary Data System. From there, it will be accessible to future scientists for years to come.

Even beyond that, the science data will continue to be worked on for decades, possibly more, depending on the research grants that are acquired.

Other team members, some who have spent most of their career working on the Cassini mission, will use this as an opportunity to retire.

Future Missions

In revealing that Enceladus has essentially all the ingredients needed for life, the mission energized a pivot to the exploration of “ocean worlds” that has been sweeping planetary science over the past couple of decades.

Jupiter’s moon Europa has been a prime target for future exploration, and many lessons during Cassini’s mission are being applied in planning our Europa Clipper mission, planned for launch in the 2020s.

The mission will orbit the giant planet, Jupiter, using gravitational assists from large moons to maneuver the spacecraft into repeated close encounters, much as Cassini has used the gravity of Titan to continually shape the spacecraft’s course.

In addition, many engineers and scientists from Cassini are serving on the new Europa Clipper mission and helping to shape its science investigations. For example, several members of the Cassini Ion and Neutral Mass Spectrometer team are developing an extremely sensitive, next-generation version of their instrument for flight on Europa Clipper. What Cassini has learned about flying through the plume of material spraying from Enceladus will be invaluable to Europa Clipper, should plume activity be confirmed on Europa.

In the decades following Cassini, scientists hope to return to the Saturn system to follow up on the mission’s many discoveries. Mission concepts under consideration include robotic explorers to drift on the methane seas of Titan and fly through the Enceladus plume to collect and analyze samples for signs of biology.

Atmospheric probes to all four of the outer planets have long been a priority for the science community, and the most recent recommendations from a group of planetary scientists shows interest in sending such a mission to Saturn. By directly sampling Saturn’s upper atmosphere during its last orbits and final plunge, Cassini is laying the groundwork for an potential Saturn atmospheric probe.

A variety of potential mission concepts are discussed in a recently completed study — including orbiters, flybys and probes that would dive into Uranus’ atmosphere to study its composition. Future missions to the ice giants might explore those worlds using an approach similar to Cassini’s mission.

Remembering Swami Vivekananda, on his 156th birth-anniversary. • Swami Vivekananda, one of India's most revered spiritual leaders, was born in Kolkata on January 12, 1863, as Narendra Nath Datta. • He was an Indian Hindu monk and a chief disciple of the 19th-century Indian mystic Ramakrishna. • He renounced the worldly pleasures in 1887 along with other disciples of Ramakrishna Paramhansa and took formal vows of sannyasa. • The spiritual leader's iconic speech at the World's Parliament of Religions in Chicago in 1893, is still remembered today. • He had a special interest in Western philosophy and history and was often assailed by doubts about the existence of God. • Through his speeches and lectures, he tried to awaken the religious consciousness among people and also tried to uplift the downtrodden using the principles of practical Vedanta. • At the World's Parliament of Religions, he took forward his message and touched upon topics like universal acceptance, tolerance and religion, which won his accolades at the international forum. • To honor his work towards youths, the Indian Government in 1984, declared January 12 as the National Youth Day and since 1985 the event is celebrated in India every year. #swamivivekanand #ramkrishnamission (at Delhi) https://www.instagram.com/p/Bsh6XSqjGa4/?utm_source=ig_tumblr_share&igshid=1xs7rskqlid10
